tion 11, the other end of the latter being receive the downwardlyextending end 13 thev rigid relation existing between said link of' thelink connection 11. By virtue of this construction it will be manifestthatv` movement on part of the gaite member 9 in a substantiallyvertical direction'will be cooperatively transmitted to effecthorizontal swinging movement on part ofl the gate structure B.

In order tozlockv the gate against movement, when the same occupies aclosed position, the member 9 is provided with adepending inger 15,which lis adjustable lengthwise ofi saidmember so that its lowerv olsetend 16 will engage with the linkconnection. 11. This maintains theklatter substanti ally rigid and prevents elevation. thereof, so thatundue pressure directed upon the gate to open the same will be overcomeby connection and the` member 9. In other words, such pressure would bedirectly eX- erted'upon the pivot point 8 of the member 9, so thatoscillatory movement onpart of the latterwill be prevented, thuspreventing undue movement on part of the gate. This constructionautomatically serves to lock the gate in its closed position withoutinvolving the assistance of outsidefastening means, and prevents thegate from being -openedby thek action of animals or other undueinfluences.

The end of the member 9, opposite the pivoted end S, is provided with anadjustable weightil?, which is employed to counterbalance the weight ofthe gate structure B when the latter is being operated, and to render.yits movement simpleK and easy to execute. By adjustingythe weightuponthe member, the mechanism A may be adapted toy gates of differentproportions, and yet will maintain the nicety of adjustment and controlnecessary in conveniently controlling movements on partofthe gate.vFurther, the weighted member serves to press the linger:v 15 intoengagement with the link connection 11, and thus renders the lockingaction of the latterl exceptionally strong and positive. Connected withthe bracket 10 is an eye 18 to which is connected a flexible cableorchain 19, the latter leading upwardly and being formed to terminatelin diverging portions 20, the endsof which being connected with theadjacent end of pivoted operatingv arms 21. The latter are pivotallymounted asfat22 uponupright posts 23,y disposed upon both sides of thegate, and

' they arms l.are so arranged as to lie substantially parallel with theroadway 6. The

other ends of the arms 21 are provided with depending operating chains2l, which terminate in hand engaging portions 25, so disposed-as to beconveniently grasped by one traveling upon the roadway 6.

Ttwill thus be seen, from the foregoing description, that when the gateis desired to be swung froma closed to an open position, the chain 2stof either arm is pulled downwardly thus causing both of the arms 21 tooscillate in unison. This results in the elevation of the cableV 19 andin the consequent vertical oscillation of the member 9. Then through thelink connection 11, horizontal swinging movement is imparted to the gatestructure B. 'It willbe appreciated that oscillating movement on part ofthe member 9, causes the linger 15 to be released from engagement withthe link connection 11, thus rendering the gate capable of swinging toan open position. Owing to the weighted construction of the member 9. itis impossible for the latter to strike a central` standing positionwhenbeing oscillated, but on the other hand is obliged to travel fromoneposition of oscillation to the other. As shown in Fig. 3, when the gateis open,vthe member 9 will engage with the end of the frame 7, so thatfurther movement on part of the gate will thus be prevented. Whenoccupying this latter position, the link connection 11 is so disposed asto prevent accidental closing movementon part of the gate, andas amatter of fact the gate is only capable ofbeing operated bymeans of thepivoted arms21. It will thus be appreciated that a vehicle driver` whenyapproaching the gate may open the latter by simply oscillating one ofthe arms 21, then after passing by the gate the latter may be closed byoscillating the other coperative arm 21, thus relieving the driverofthenecessity of gettingout ofhis vehicle t0 move the gatefrom one,yposition to the other. This feature being particularly desirable duringperiods of inclement weather. While I have described the aboveconstruction in connection with .a particular form of gate, it will beappreciatedv that the mechanism A in realityl simply constitutes a gateattachment, and may therefore be used in connection with all gates Ofaswingmg type. v
